Answer:
y=6
Step-by-step explanation:



The first seven prime numbers are 2, 3, 5, 7, 11, 13, 17
If you multiply all those numbers together, you'll have a product with 7 different prime factors (each of the numbers you multiplied).
So, 2 x 3 x 5 x 7 x 11 x 13 x 17 = 510,510
Answer:
2.1 hrs
Step-by-step explanation:
In 1 hr, Phillip would have proofed 1/7 of the chapter. In 1 hr, Kim would have proofed 1/3 of the chapter. So, together in 1 hr, they would have proofed 10/21 of the chapter. So, it would take 21/10 or 2.1 hrs to proof the whole chapter together.
Answer:
sinA = ± 
Step-by-step explanation:
Using the Pythagorean identity
sin²A + cos²A = 1 ( subtract cos²A from both sides )
sin²A = 1 - cos²A ( take the square root of both sides )
sinA = ±
